SU PPORTING DEVICE FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 515,664, dated February27, 1894.

Application filed September 29, 1893. Serial No. 48636 (N0 mOdBL) TooiZl whom it may concern:

Be it known that I, EDWIN D. EATON, a citizen of the 'United States ofAmerica, residing at Fairfield, in the town of Russell, county ofI-Iampden, and State of Massachusetts, have invented new and usefulImprovements in Supporting Devices for Bicycles, of which the followingis a specification.

The present improved stand for a bicycle is designed as a permanentattachment to the machine, the object being to produce a device which isso light and convenient in its arrangement as to constitute noincumbrance, and so readily operated that the supporting 'member may bemoved down at pleasure and easily confined in its supporting bicycleposition, or, on the other hand, elevated and so held from itssupporting position, when desired to ride the vehicle.

The invention consists in the construction and combination of partssubstantially as will be hereinafter described and pointed out in theclaim.

The device is fully and clearly illustrated in the accompanyingdrawings, in which- Figurel is a side elevation of a safety bicycle withthe supporting attachment thereon, the latter being shown as held in itselevated or non-supporting disposition, as necessary while the machineis being ridden. Fig. 2 is a vertical sectional view taken across anintermediate part of the framing of the machine and centrally andlongitudinally through the supporting attachment, the supporting memberproper being shown as held in its lowered and supporting position. Fig.3 is a perspective view of the attachment clip and Fig.4 is aperspective view of the guide-tube.

Similar letters of reference indicate corresponding parts in all of theviews.

A represents the attachment clip which is in the form of a split collarwith the adjacent perforated ear-pieces, a, c.

B represents the guide-tube which is surrounded by the attached collar,d, having the laterally extended hub or boss, d with the screw-threadedhole, C1

The clip surrounds the lower forward di agonal frame member, oc,-orother suitable frame member, according to the style of frame with whichthe bicycle is equipped,-the confining constriction and support of thetube both being insured by the headed screw, f, which passes through theapertu red ear-pieces and with a screw engagement with the screwtappedhole in the boss at the side of the vertical guidetube.

C represents the support-rod which plays longitudinally within andthrough the guidetube it having at its bottom the oppositely extendedand suitably formed bearing members or feet, g, g. The guide-tube hasthrough its side a slot, 71, which, while extending a considerableportion of the length of the tube, has a gradual spiral inclination, asseen at 71 while the rod has the stud, 1', extending outwardly therefromthrough, and impinging against the boundaries of, the slot so that indescending the rod has a rotative movement to the extent of a quarter ofa turn. It will be seen that the lower portion of the said slot againstwhich the letter, h, is placed, is lougitudinal of the tube andnon-spiral while the spiral portion is above such non-spiral portion. Bythis formation the rod, 0, in its descent, has its quarter turn beforemoving ontirely down so that it will certainly be in itsbicyclesupporting position, with the feet, g, g, transverse, on alloccasions,inequalities in the ground being immaterial. The upperextremity of the guide-tube is longitudinally split, as at j,-to becontractibleexteriorly screw-threaded as at k, and tapered as at Z.

D represents a grip-nut having the internal tapered or contractedformation, as seen at no, so thaton screw-engaging the threaded upperend of the tube it will exert a contracting impingement upon the splittube to constrict it about the rod and hold it in either its elevated orits lowered position.

When the machine is to be ridden and the support-rod is held elevated,the foot-bearing points are longitudinal with the machine, as indicatedin Fig. 1, but when'the grip-nut is partially unscrewed and the rodpermitted to fall, it automatically makes a quarter of a turn bringingthe foot-bearing points transversely, as seen in Fig. 2.

The grip-nut may have the lever handle extension, 0, to facilitateturning it, and the support-rod may have the cross-head, p, at its upandconfinedwithin said collar and which has I per end for convenience inraising the rod. the spirally inclined slot, of the rod which is Havingthus described my invention, what longitudinally and rotatively movablein and I5 I claim, and desire to secure by Letters Patthrough said tubewith the oppositely ex- 5 ent,istended bearing points or feet, and meansfor The combination with the constriction clip temporarily confining therod against move for an encircling connection upon a rigid bar ment,substantially as described. or member of the bicycle frame,a collar with1 a laterally extended hub, and the constricting EDWIN 10 screw whichpasses through the ear-pieces of Witnesses:
